START UP / OPERATION

Electrical Supply 
 

 
 
 

 

 
Wiring of the unit is complete when it is
shipped  from the factory. The unit is
supplied with a three conductor
electrical cord which extends from a
side of the unit. Plug the unit into
correct grounded outlet. It is
recommended that a separate circuit be
run for each cabinet to prevent the
possibility of another appliance blowing
a fuse, causing subsequent loss of
product. 
 

Temperature Control 
IMPORTANT 

This unit has dual temperature range
freezer / refrigerator. 
For refrigerator mode, turn UP toggle
switch. For freezer mode, turn DOWN
toggle switch. This switch is located
below the warning light. 
You can change the temperature range
(freezer / refrigerator, or refrigerator /
freezer) without turning off the
condenser unit.      
 
The flow of room air over the top of the
Spot Merchandiser should be minimized
for best refrigerating results. Avoid
placing your Spot Merchandiser in the
direct rays of the sun or in the air 
stream from electric fans or open
doorways. 

High Pressure Switch 

A high pressure limit switch is provided
on all Spot Merchandiser Models. This
switch is used to limit the discharge
pressure of the compressor. 
 
This switch will automatically cycle off the
compressor and turn on a warning light
on the base, when the discharge
pressure in the system is too high. 
 
If this condition occurs, first clean the
condenser. If the warning light continues
to illuminate, call service. 
 
This pressure switch is a safety device
and will not function during normal case
operation. Do NOT remove it from the
system. 
 

Draining 

The case is equipped with a bottom drain
tube and a plug for removing water
during defrost and cleaning process.
Keep the plug connected to avoid air
leaks.
